Another day, another random white iPhone 4 spotting. This time it's at Best Buy, and it's not even the smartphone itself but rather empty shelf space!

The iPhone 4 shaded in white has suffered delays since the latest Apple smartphone was first introduced in June. First it was delayed until late July and then late 2010. The Cupertino giant has remained mum since, although there have been quite a few random sightings along the way.

And now we have this: a sign that is supposedly posted in a Houston Best Buy location revealing the iPhone 4 in white at an unlocked price. Do you believe it? While it's likely authentic, that doesn't mean it's coming anytime soon. Engadget also recently posted a lengthy exposé as to why the white iPhone 4 has been delayed, but I say Apple should just move on, work on the next generation of the iPhone and forget all of this ever happened.
